  "question": "What are the odds of accidentally swallowing a live bee or wasp and suffering a life-threatening airway reaction?",
  "quick_answer": "About 1 in 29,000 US adults over a lifetime end up in an emergency department with a mouth or throat sting from a swallowed bee or wasp, and roughly 98% of those are treated without hospital admission. Frequent outdoor drinkers tend to imagine it happening far more often than it does.\n",

    "description": "The \"bee in the soda can\" scenario is one of the more vivid and widely circulated outdoor hazard stories. Social media amplifies occasional case reports of people who swallowed an insect, felt a sting in the throat, and required emergency treatment, which inflates the perceived frequency considerably relative to the actual rate. Most people who have spent summers drinking outdoors overestimate how often this ends badly.\n",

Annual probability: 195 / 335,000,000 ≈ 5.8 × 10^-7. Compounded over 59 years of remaining adult life: 1 - (1 - 5.8e-7)^59 ≈ 3.4 × 10^-5 ≈ 1 in 29,000. The uncertainty band carries the study's own 95% CI through the same lifetime compounding (2458.55–5320.79 over 20 years → ~123–266/year). \"Oropharyngeal sting\" is broader than the specific can/bottle-drinking scenario, but the NEISS study is the only US surveillance source that directly quantifies this route.\n",
